Introduce current in url

[JuanitoFatas]

Hi 👋🏼

I think it would be nice to introduce current in url: https://rubyapi.org/current/o/binding, which pulls content from latest current ruby version: https://rubyapi.org/3.1/o/binding

This idea is inspired by Postgres docs: https://www.postgresql.org/docs/current/ddl-partitioning.html that is same as https://www.postgresql.org/docs/14/ddl-partitioning.html as of 2022-09-19.

Thanks for considerations.

A slightly different approach is for current to redirect to the stable version, which is what ruby-doc.org does. e.g. https://ruby-doc.org/current/Module.html#method-i-ancestors redirects to https://ruby-doc.org/3.2.1/Module.html#method-i-ancestors. I'm unsure which I prefer.

Honestly, it's just what we've got flagged as the default version, right?

rubyapi/config/ruby.yml

Line 4 in 0a3500c

default: true

Going off of what you said, we make https://rubyapi.org/current/o/string look up the default version, and redirect to https://rubyapi.org/3.2/o/string, right?

Basically, yeah. There might some cases where a class/module is removed/renamed in a newer version of Ruby, so the redirect could be invalid, but I imagine that would be rare.
